#5 Drew McIntyre could still be in the WWE Title picture after RAW

Drew McIntyre finally returned after being absent from RAW last week. Naturally, he was anything but happy about the way his second WWE title reign ended.

While we thought that Drew McIntyre vs Sheamus was a possible WrestleMania 37 direction, we were wrong. They had their payoff match on free TV to open RAW, and it was a solid half-an-hour bout.
We usually don't get to see singles matches go on as long on RAW that often, so it was nice to see. Drew McIntyre's exclusion from the incidents between The Miz and Bobby Lashley means that he is almost certain to be in the WWE Championship picture at WrestleMania 37.
Does this possibly mean that Brock Lesnar isn't returning on time for the show of shows this year? Has he been approached yet? Brock Lesnar isn't on WWE contract (that we know of, anyway). Is Drew McIntyre going to get another coronation at WrestleMania 37?
